Lrbho maybe works - JP Enterprises EnhancedBolt 9mm AR Bolt Carrier Group (BCG) Kit - JP Short Silent Capture Spring

So let’s talk about the elephant in the room. Your LRBHO only works on certain uppers with this bolt. On my set up it doesn’t. Rather frustrating since that’s why I spent more money on the “enhanced bolt”. This set up does run smooth. You can definitely tell the difference with this setup. Recoil is definitely dampened down. I’m mildly disappointed with the bolt and the fact that the LTBHO doesn’t catch. Maybe I should try some hotter loads in it but with standard Remington 9mm ranger ammo and Glock mags there’s no way it will hold open
